Cooking up trouble.
Nancy's added the just-washed strawberries into the mix. Then she put the top on and hit the BLEND button. The mixture inside quickly became a pinkish-red mush.
Mmmm! Nancy thought. My smoothie is going to be awesome!
The smoothie continued bubbling. . . and bubbling. . . and bubbling. Nancy stared at it. Her smile froze on her face. Something was wrong. There were way too many bubbles. In fact the bubbles were pushing against the top of the blender. A few seconds later the top fell away, and the bubbly mixture came pouring out of the blender and onto the counter. Nancy gasped. Her smoothie was going out of control!
